From the early inflatable
sex doll to the current silicone/TPE sex dolls and even sex robots, real dolls have become more and more emulated, but also more uses, from just sex toys to realistic sex dolls that can now act as humanoid models or Butler robots, or as works of art, convey the infinite possibilities of dolls. It must be said that while developing the toy market, it is also a new understanding of "sex" in human society. From adult products to sex industries, every development across the age reflects the constant evolution of humanity in sexual attitudes and sexual behavior.
